NRS conﬁguration

The Mobile Communication Gateway 3100 (MCG 3100) is defined as a

Dynamic Gateway Endpoint on the Network Routing Server (NRS) SIP

Proxy Server (SPS) and is assigned an endpoint name. Authentication

is turned off. The endpoint name is configured on the MCG 3100 as the

gateway name under the list of gateway configuration parameters.

Each Mobile Communication Client 3100 (MCC 3100) or MC 3100 Web

User Interface user is represented by an NRS-SPS User Endpoint (UE).

The UE is created in the L0 domain that corresponds to the Private Branch

Exchange (PBX) that hosts the user. The NRS-SPS must be configured

so that the NRS-SPS will never match a destination number against the

UE that represents an MCC 3100 (not even the corresponding Universal

Extension [UEXT]).

The user endpoint entry on the NRS-SPS for MCC 3100 defines the

username and corresponding password only, and is not used for SIP

routing.

All calls to the MCG 3100 are prefixed with the mobile prefix. A routing rule

is associated with the MCG 3100 endpoint to route all calls with this prefix

to the MCG 3100. This routing rule, and not the user endpoints, ensures

calls route to the MCG 3100.
